BPC-157

In a rat model of lower-extremity ischemia-reperfusion injury, BPC 157 was reported to be associated with lower oxidative-stress and apoptosis markers and with better-preserved skeletal muscle structure and reduced fibrosis compared with untreated injured controls. Findings are preclinical and from animals only.

In a rat tracheocutaneous-fistula model that combined the pentadecapeptide BPC 157 with nitric-oxide-system agents, the report described accelerated closure of skin and tracheal defects together with macroscopic and microscopic healing changes relative to control animals.

In an ex-vivo organ-bath (myograph) study using isolated human internal mammary artery rings obtained as residual tissue from coronary artery bypass graft surgeries, BPC 157 was reported to produce a concentration-dependent relaxation of phenylephrine-precontracted rings, greater in endothelium-intact than endothelium-denuded rings, attributed predominantly to an endothelium-dependent nitric-oxide pathway. Findings are limited to isolated human arterial tissue.

This narrative review synthesizes preclinical literature on BPC-157, a synthetic pentadecapeptide, describing reported associations with angiogenesis, collagen synthesis, fibroblast activity, and nitric-oxide-pathway modulation in tissue repair and pain. The authors note that human data remain limited and controlled clinical trials are still needed.
